While Brittny Gastineau's alleged attacker Retna claims the scary hotel brawl that left Brittny Gastineau with a black eye was mutual, the street artist Retna actually has a history of being violent!

All in the past two years!

In 2012 he was charged by police with 3 counts of battery for punching two employees of an art gallery in the head, and then later coming back to hit another one! Retna was ordered to stay away from the art gallery after that incident.

Then last July Retna was accused of harassing two art gallery employees while also destroying paintings on display using a knife and some beer bottles.

Both of the employees got restraining orders against Retna, and one employee claims Retna attempted to put his hands around the employee's throat and also said:

"Next time I see you I'm going to take your TONGUE out of your mouth n wrap it around your nexk and staple ur ass to the backboard n charge the kids in the neighborhood 25 cents. To throw rocks at ur some n stone u to death. Booyah."

Wow! That is way too specific!

It's clear that Retna does NOT like art galleries, and that he's also capable of some kind of extreme violence!

Will his past come back to haunt him in this latest court case of his?

So 19 yr. old Chris Brown paid with consequences. Society decides that wrong-doing has to b paid for. He paid his debt. to society. Then u have guys like this, Sean Penn, and the list goes on who have a "history" of life-long violent behaviour and…

In July, father John McCain was diagnosed with stage 4 glioblastoma, an aggressive form of brain cancer, which also claimed Beau's life.

When the 33-year-old began crying, the politician went over and consoled her, adding:

"There is hope... And if anybody can make it, your dad [can]."

Biden is also optimistic about "breakthroughs that are occurring now," regarding potential treatment options and cures.

"There's a lot of things happening. Any of you who have somebody who is diagnosed with gliobastoma, which is about as bad as it gets, there's breakthroughs that are occurring now... And it can happen tomorrow."
